Two complexes that have entered clinical trials as anti-cancer drugs are [HIm][RuCl 4 (im)(DMSO)] and [HInd][RuCl 4

Question:

Two complexes that have entered clinical trials as anti-cancer drugs are [HIm][RuCl4(im)(DMSO)] and [HInd][RuCl4(Ind)2]. In the search for related active complexes, [RuCl2(DMSO)2(Biim)] and [RuCl3(DMSO)(Biim)] have been tested; the latter is more cytotoxic against selected human cancer cell lines than the former.
